Generally to enter test mode the unit has to be disconnected from mains. Then you connect it, wait 20-30 sec, put the unit in Option 1, and start test mode: SHIFT90258 then you press CD and enter mode numer.  Not sure if it works on Mark I but please try.

Thank you very much!! Very useful advice

Thanks, Peter. I couldn't figure out how to get mine in test mode, so I assume it doesn't exist on Mark I. I bought a disk with small embedded brushes. The challenge I had is that the player wouldn't rotate the disk since it couldn't focus (I assume). I finally got it to work by manually rotating the disk, which cleaned the laser sufficiently to start focusing and then run the disk autonomously. It works fine now.

The sequence works for every model.
Make sure that RADIO or CD shows in your BEO4 display when you enter the numbers. 

Thanks, Beobuddy. I couldn't get it to work, even though I followed the general directions. Shift is the "Back" button on the remote, right? And is the number code the same for Mark I, II and III?

Appreciate the help.

Chris,

you have to add SHIFT command to LIST buton of Beo4. Then you chose that command and press OK.

This is not needed to get the BS9000 in testmode. 

First thing (when speakers are not connected to the BS9000 directly) is to set the BS9000 in A option 1. The standby led has to blink once to confirm the command. If it doesn't respond, then it might be a faulty infrared receiver.

After the BS9000 confirms the Aopt 1, it will go in testmode.
